6 Moly S31254

254SMo, UNS S31254, 6 Moly Alloy

UNS S31254 (Equal and Superior Than 254 SMO,EN 1.4547) is an austenitic stainless steel of the ELC type developed for use in seawater and other aggressive chloride-bearing media. The steel is characterized by the following properties:

Metallurgical structure Alloy 254SMO is face-centered cubic lattice structure. In order to obtain austenitic structure, 254SMO general annealing in the 1150-1200degree.In some cases, the material maybe with the traces of metal middle phase (x phase and & alpha phase). However,their impact strength and corrosion resistance are not adversely affected in normal circumstances. When placed in the range of 600-1000degree, they may phase in the grain boundary precipitation.
